CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 357,999, dated February 15, 1887.

Application filed October 11, 1886. Serial No. $5,829. (No model To all whom it may concern:

Be it known that we, EDWIN PYNoHoN, ATHOL B. MAoKLIN, EDWIN F. MULLoY, llIIOHAEL MoDERMorr, and WILLIAM D. OBRIEN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Axle Lubricators, of which the following is a specification.

Our invention relates to improved devices for lubricating car-axles, and has for its objects to supply the deficiencies of former similar devices, and particularly to provide a support for the spiral coil of lubricant-carrier used. We attain these objects by the mechanism illustrated in the accompanying drawings, wherein- Figure 1 is a sectional view of a caraxle box with our improved lubricator in position. Fig. 2 is a perspective view of a lubricator with lubricant-carrier partly removed to show its support. Fig. 3 is a vertical section through the lubricator. Fig. 4 is a detail view of the carriage-spring- Like parts are indicated by the same letter in all the figures.

A is the car-axle box. 13 is the axle; O, the bearing-surface at the top of the box.

D is a spool having the spiral E formed about its surface. Between the coils of the spiral lies a spiral of lubricant-carrier F of any de sired material. This latter coil is supported by a metallic support passing through it. This support may be made in many ways and of various materials; but the form which we think best is that showna spiral coil of wire, G, twisted and formed into another coil with the lubricant-carrier.

H is the central shaft rigid with the spool and bearing at each end on the carriage end bars, I I.

J is a double spring having the curved ends, as shown,with the flat central portion, N. This spring passes into the groove R on the lower side of the carriage end and the edges of the fiat portion pass over the ledges P P. A bolt, M, is now passed through the spring into the carriage end, and thus the spring is secured against any kind of motion. On the ends of the spring are buttons 0 O.

K K are projecting ends on the end bars.

L L are downward] y-curved bars, which connect the two end bars, and thus form the earriage-frame. I

The use and operation of our invention are as follows: The carriage-frame is put together of suitable size and shape to accommodate the box in which it is to be used. The projecting ends K K may or may not be used. The rods L L are of metal which will bend, so that by bending them the length of the carriage may be altered, andwhen bent the lubricator may be easily introduced into the box. A spool like-that shown in Fig. 3,0f the desired length and shorter than the carriage, is now taken, and a coil of lubricant-carrier, with its interior support, is placed between the folds of the spiral and firmly pressed into position and secured. The spool is now placed in position on the carriage and the whole introduced into the box in such position that the top of the spool will bear flexibly against the axle, and the lower side of the same will dip into the lubricant in the bottom of the box. As the axle rises or falls, through the action of the heavy jolts, the spool follows it and always bears against it. When the axle pushes to one side, as in turning a sharp bend, the spool slides laterally in its bearings on the end pieces and still follows the axle and retains its position. The support in the spiral coil of lubricant-carrier protects the same against becoming too much compressed and also keeps it fromwearingaway. Thebuttonsonthespring permit them to slide freely on the box. The spring, attached as shown, has a free motion, except at the flat central portion, and it can be easily put into position after being bent and tempered.

If the castings for the end pieces are made as shown, by taking off any quantity at the end the width of the carriage may be varied at will and at the same time the position of the rods L L can be altered so that they will be nearly at the extremities of the end pieces, or near the spool.

The central spool-rod is made of steel and the outer part of the spool is cast thereon. This is to give greater strength to the bearing parts. The wire coil may be close and so as to fill the spiral groove, in which case the asbestus or other similar material may be partly or entirely dispensed with.

The coil of wire or wire and lnbrieant-earrier might be coiled around the central rod or core in a spiral without use of the spirallygrooved outer part of the spool.

We clain1- 1. In a car-axle lubrieator, the combination of the end bars of the carriage-frame having along their lower sides dependent ribs with inner edges, so as to form a groove, as shown, with double springs, shaped as shown, and adapted to be received into such grooves and secured to the said bars.

2. In a car-axle lubricator, a lnbrieantcarrying spool consisting of a central steel rod, a metallic portion cast about such rod, and a lubricantcarrier secured to such metallic portion.
